What creates the reaction force in a vertical circle?
AI Thread Summary
The reaction force in a vertical circle, such as a cyclist going upside down, is produced by the combination of gravitational force and the force exerted by the track. Gravity acts downward while the centripetal force, necessary for circular motion, is directed toward the center of the circle. This centripetal force is calculated using the formula mv²/r, where m is mass, v is tangential speed, and r is the radius of the circular path. The forces acting on the bike ensure it maintains its circular trajectory. Understanding these forces is crucial for analyzing motion in vertical loops.
I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19.
For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...
Let's declare that for the cylinder,
mass = M = 10 kg
Radius = R = 4 m
For the wall and the floor,
Friction coeff = ##\mu## = 0.5
For the hanging mass,
mass = m = 11 kg
First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on.
Force on the hanging mass
$$mg - T = ma$$
Force(Cylinder) on y
$$N_f + f_w - Mg = 0$$
Force(Cylinder) on x
$$T + f_f - N_w = Ma$$

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is
The second part of the problem is exactly why you get this affect.
